A 24-year-old Minchinbury Jets soccer player has been charged for assaulting a teenage boy during a game at Laybutt Reserve in Blacktown at 3.20pm on Sunday.

The 16-year-old lineman’s jaw was fractured during the alleged assault.

The Glenmore Park man attended Blacktown police station on Thursday afternoon where he was charged with common assault.

The Blacktown Workers Football Club junior was allegedly assaulted by several Minchinbury Jets players, one of whom police said punched the boy in the face, 20 minutes into the All Ages division 6 men’s game against the Workers at their home ground.

The boy fell to one knee and the alleged attack only stopped when spectators intervened, police said.

The Jets player was granted bail to appear at Blacktown Court on June 20 on the condition he doesn’t approach the alleged victim or visit Laybutt Reserve.

Blacktown police are appealing for witnesses who were at the soccer fields at the corner of Reservoir Rd and Penny Pl next to the Blacktown Workers Sports Club.

The boy was rushed to Westmead Hospital to see a plastic surgery but won’t require surgery, a witness told the Advocate.

The witness, who spoke on condition of anonymity and was at the game, said the boy’s family was "distressed" over the incident.

The alleged attack is believed to have been prompted over an offside call when a number of Minchinbury players confronted the boy.

One of the Jets players was sent off after the attack and the Blacktown Workers players didn’t retaliate, the witness said.

The game wasn’t called off and ended in a 2-2 draw.

Blacktown & District Football Association CEO Jack Taylor said the judiciary would address the incident on Monday and report its findings to him early next week.

Mr Taylor said the association wouldn’t make any comment on the assault.

Detectives are asking for anyone who was present and witnessed the alleged assault to contact them on 9671 9199 or Crimestoppers 1800 333 000.
